Should i go and be tested if i have the following symptoms for 3 days: severe migraine, sore throat, nausea, body aches, chills, cough occasionally and a temperature on the 1st day?

Covid-19 symptoms include fever/chills, cough, fatigue, muscle/body aches, headache, sore throat, loss of taste/smell. Assume you are positive and self isolate for 14 days to prevent spreading the disease. See a Dr for worsening difficulty breathing, Blue lips/nails, persistent chest pain, confusion/lethargy. Testing may be needed for you to go back to work after you recover.

Get tested. You are best advised to get this out of the way if present. And yes, when cleared, get your vaccine
